Abstract
L'invention concerne un procédé pour la séparation de 99mTc à partir de cibles en molybdène. Le procédé pour la séparation d'isotope 99mTc à partir de cibles en molybdène comprend : i) l'utilisation d'un mélange initial d'éléments à plusieurs constituants, le mélange contenant du 99mTc ; ii) la dissolution du mélange d'éléments à plusieurs constituants avec un agent oxydant pour oxyder le mélange d'éléments ; iii) le chauffage du mélange d'éléments à une température suffisamment élevée pour sublimer un composé vaporisé contenant du 99mTc ; iv) la condensation du composé vaporisé contenant du 99mTc pour former un produit réactionnel ; v) l'ajout d'une base au produit réactionnel condensé pour dissoudre le produit réactionnel contenant du 99mTc pour former du pertechnétate de sodium (Na99mTcO4) ; et vii) la purification de la solution brute de pertechnétate de sodium Na99mTcO4 à l'aide de la chromatographie sur colonne pour obtenir l'isotope 99mTc en tant que composé radiochimique.
